The Rio Grande serves as the focal point for this 2016 international border survey, defining the winding boundary between Texas and Chihuahua, Mexico. The landscape is characterized by its drainage network, where the Quitman Arroyo and Davis Arroyo cut through the arid terrain of Hudspeth County. Significant natural landmarks such as Big Tank Canyon and the curiously named The Little Box provide geographic orientation in an area largely defined by its topographical relief. A single primary access route, Indian Hot Spring Rd, traverses the northeast corner, illustrating the limited infrastructure and remote character of this desert region near the United States and Mexico border.
